Installation
------------

[](#installation)

```
composer require beste/in-memory-cache
```

Usage
-----

[](#usage)

```
use Beste\Cache\InMemoryCache;

$cache = new InMemoryCache();

$item = $cache->getItem('key');

assert($item->isHit() === false);
assert($item->get() === null);

$item->set('value');
$cache->save($item);

// Later...

$item = $cache->getItem('key');

assert($item->isHit() === true);
assert($item->get() === 'value');
```

You can also provide your own [PSR-20](https://www.php-fig.org/psr/psr-20/) clock implementation, for example a frozen clock for testing, for example from the [`beste/clock` library](https://github.com/beste/clock).

```
use Beste\Clock\FrozenClock;
use Beste\Cache\InMemoryCache;

$clock = FrozenClock::fromUTC()
$cache = new InMemoryCache();

$item = $cache->getItem('key');
$item->set('value')->expiresAfter(new DateInterval('PT5M'));
$cache->save($item);

$clock->setTo($clock->now()->add(new DateInterval('PT2M')));
assert($cache->getItem('key')->isHit() === true);

$clock->setTo($clock->now()->add(new DateInterval('PT5M')));
assert($cache->getItem('key')->isHit() === false);
```
